If you have an iPad, you can use the app Duet. I used it for college back when I only had a laptop and and iPad and it worked surprisingly well.

There’s some lag and you’ll need to install some software on the PC as well, but it’s pretty lightweight if I remember correctly

Noob question

Whenever I search for 1337x or any other site someone recommends, how do I know which one is reliable? Because if I search in Google, DuckDuckGo, or any other search engine, I get results with domains ending in .is .to. .tw .skin .net etc.

Are they all just different proxies to the same thing or is there a list of reliable links?
